In a medium bowl, combine cream cheese, shredded cheddar cheese, roasted red peppers, green onions, garlic powder, and cayenne pepper. Mix with a wooden spoon until evenly combined. Season with salt and pepper to taste.

Cover the cheese mixture and chill in the refrigerator for about an hour.

Prepare your selected coatings by placing them on small plates. Use crushed Nacho Cheese Doritos, paprika, and black sesame seeds as coatings. To crush the Doritos, place them in a plastic bag and smash them with a rolling pin until you have fine crumbs.

Using a tablespoon measuring scoop, portion out the cheese mixture and roll into balls. Continue until all of the cheese mixture is used.

Roll each cheese ball in your selected coating(s) and set aside.

Use a wooden skewer to make vertical lines up the sides of each ball and across the top to create a pumpkin-like appearance.

Insert half of a pretzel stick into the top center of each cheese ball to resemble a pumpkin stem. Garnish with a small parsley leaf if desired.

Refrigerate the mini cheese balls until ready to serve.
